Answer
Run a solar software trial against defined workflow requirements and representative authorized project cases. Retain inputs, configuration, assumptions, reviewed outputs and failed or untested tasks. Check revision handling, receiving-team usability, manual dependencies and written access or export terms before choosing, rejecting or extending evaluation. A trial does not establish engineering approval or guaranteed productivity.
A software trial should end with an evidence-backed buying decision. A polished demonstration is useful for orientation, but your team also needs to know what happens with its own inputs, revisions, reviewers and exports. Evaluate the work you intend to perform, including exceptions that are common in your projects.
This is an operational evaluation method, not proof of engineering accuracy, regulatory acceptance or future commercial results. Keep customer identifiers and confidential files out of a trial unless their use, provider access and retention are authorized.
Define the decision before opening the trial
Write down the workflow being evaluated: residential layout, commercial production modeling, electrical documentation, proposals or another bounded task. State which roles will use it and which outputs must be delivered. A tool may fit one stage without covering the whole project.
Separate mandatory requirements from preferences. For each requirement, define observable evidence: an editable geometry correction, a supported equipment model, a source-labeled analysis run, an export your receiving team can use, or a permission restriction you can test. Do not substitute a feature name for a completed task.
NASA’s decision-analysis guidance describes evaluating alternatives against criteria and recording the decision basis. Adapt that approach to procurement; NASA guidance is not a solar-software certification or a mandatory scoring system.
Use representative cases and the same comparison basis
Choose cases that expose your actual workload, not only the easiest demonstration site. Useful cases may include a routine roof, a constrained site and a revision with missing information. The number and trial duration depend on scope, access and review capacity; there is no universal minimum that proves fit.
Retain the input package, equipment version, assumptions and expected deliverable for each case. When comparing tools, reconcile weather sources, geometry, loss treatment, output boundary and analysis period before interpreting different production results. Agreement between tools does not establish accuracy, and a difference alone does not identify which result is wrong.
| Test | Evidence to retain | Question for the buyer |
|---|---|---|
| Create the initial project | Source files, input mapping and unresolved fields | Can the team start without invisible defaults? |
| Correct a roof or equipment choice | Before/after revision and affected outputs | Which dependencies update and which require manual review? |
| Model production | Inputs, model/version, units and assumptions | Can a reviewer reconstruct the result? |
| Prepare a proposal | Accepted design reference, scope and financial basis | Does the customer output describe the current project? |
| Transfer work to another role | Export, receiving task and return reason | Can the next person use it without private coaching? |
| Retrieve or exit the trial | Accessible files and written retention/export terms | What remains usable when access ends? |
Keep trial outputs preliminary until the responsible reviewers authorize their use. A completed test is not permit approval or permission to operate.
Measure completed work, including corrections
Record active task time separately from waiting for vendor help, missing inputs or reviewer decisions. Include the time required to correct an output and transfer it. State the task boundary and whether the operator had training or live assistance.
Do not compare an experienced user of one tool with a first-time user of another without disclosing that difference. Report failed or uncompleted tasks alongside successful ones. A small trial can reveal specific limitations; it cannot support a universal productivity or conversion claim.
Confirm the commercial and data terms
Obtain current written terms for trial access, included functions, user roles, usage limits, paid dependencies, export formats, support, data location and deletion. Confirm what changes when the trial ends. Do not assume that a public free-trial offer includes every feature or that a demonstration establishes an integration available in your configuration.
For SurgePV, request a guided evaluation using a sanitized case and ask the vendor to demonstrate the required design workflow and outputs. Record what was demonstrated, what was described but not tested and what remains unavailable or unknown. This guide does not establish a trial length, free access, pricing or native automation.

DECISION / CONDITIONS / OWNER / REVIEW DATE:Choose, reject or extend evaluation based on the requirements that matter. An unresolved mandatory requirement should remain visible in the decision. After selection, use the software adoption workflow to plan training, controlled rollout and ongoing support; choosing a tool and establishing daily use are separate tasks.
